I have an idea for an addition to the HUD. Several abilities like Renekton's slice and dice, Fiora' lunge, and Lee Sin's Q, W, and E when casted, have a certain time to use another ability after. I also hear rumors of Darius getting a similar mechanic for his Ultimate. Currently, when using the spell, the icon dulls out until the time limit runs out, without the player's knowledge(unless you count the amount of seconds). I have an idea where after using such ability, the icon has a counter-clockwise rotation (opposed to the clockwise cooldown rotation) representing the amount of time left until the use again, after the counter-clockwise rotation ends, the normal clockwise rotation begins. This won't make a really big difference, but when jungling with Lee Sin I could find it slightly helpful.
